我国柳枝稷规模化种植现状与前景

柳枝稷是国际上公认的最适合作为生物燃料的能源植物。我国目前柳枝稷的种植规模不大,处于引种的初级阶段。柳枝稷引种主要集中在我国北方,南方尚未见报道。本研究简要叙述了我国柳枝稷引种历史和种植现状;根据近年来引种柳枝稷出现的问题,分析阐述了柳枝稷种植过程中的技术问题,以及我国柳枝稷种植的前景。作为一种有效的水土保持植物、优质牧草,能够在废弃的工矿地、盐碱地和不适宜农作物种植的地区种植的第二代能源植物,柳枝稷在我国有着广泛种植前景,需要政府-企业-农户有机的结合,有计划的引种种植。

Present status and future of switchgrass going to scale plantation in China

Switchgrass is internationally recognized as the most suitable biofuel plant.The planting scale of switchgrass is relatively small in China,so the introduction of switchgrass is still in the initial stage.Switchgrass is mainly introduced to northern part of China while it is not reported that there is an introduction of switchgrass to southern part of China.The introduction history of switchgrass and its cultivation status were briefly described in this paper.According to the problems appeared in the process of introduction,we analyzed the technical problems in switchgrass planting and the prospect for planting switchgrass in our country.It has prosperous prospects for switchgrass plantation in China because it was reported that the switchgrass is an effective soil and water conservation plant and is a high-quality forage.As the second generation bioenergy plant,switchgrass could be planted in abandoned sandpits,saline-alkali soils and lands unfavorable for crop production.However,in order to introduce switchgrass systematically,a closely cooperation among enterprises,government and farmers is still needed.
